PUMP FOR RAISING WATER NEAR RAILROADS.

SPECIFICATION forming part of Letters Patent No. 464,361, dated December1, 1891. Application iiled February 18,1891. Serial No. 382,002. (Nomodel.)

To all whom t may concern:

1 3e it known that I, CHARLES HoDGsoN, a British subject, residing atJacksonville, in

the county of D uval and State of Florida, have. invented certain newand useful Improvements in Pumps for Raising lVater near Railroads; andI do hereby declare the following to be a fu'll, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to pumping up water for filling tanks and for otherpurposes at railway-stations; and it consists of certain novel deviceswhereby the locomotive moving on the rails furnishes the necessary powerfor pumping the water out of a Well or underground reservoir into anoverhead tank.

My invention consists of a long cylindrical pump-barrel connected ateach end to a suction-pipe leading to a well or underground reservoir,and also having at each end a discharge-pipe leading into the overheadtank. These various pipes are connected by suitable lifting-valves, allopening upward. The long cylinder -has a piston connected to an endlesswire rope, which forms the piston-rod, and the pump is driven by themoving locomotive grappling the upper part of this endless wirepiston-rod.

Reference is had to the accom panying drawings, wherein the same partsare indicated by the same letters.

Figure l represents a sectional View, partly in profile, of one form ofmy device when two wells or underground reservoirs are used. Fig. 2represents a modification of my device where only one reservoir isemployed. Fig. 3 represents one method of connecting the ends of thewire rope together and to a car.

IV, IV', and W2 represent wells or underground reservoirs, and T theoverhead tank.

A represents the pump-barrel, preferably laid horizontally beside therailroad B in a trench at. a somewhat lower level than the rails. Thispump-barrel may be of any required dimensions, preferably from twelve tosixteen inches in diameter and from thirty to forty feet in length orupward, according as it be desired to pump the water required by severalshort movements of the locomotive or all at one long stroke as thelocomotive is leaving the tank.

V V V represent the various valves, all of which open upward and closetightly at the first downward pressure. The action of these valves willbe apparent when we consider the motion of the piston P alternately fromend to end of the pump-barrel. The said piston P fits snugly in the longpump-barrel and is secured to the wire rope R, which thus forms aiieXible piston rod. The wire rope is sewed with hemp and passes throughstuffing-boxes S at each end of the pump-barrel. This wire rope goesover sheaves or drums D and D', and the two ends are connected by aturn-buckle or some other adjustable device at H', a point on the wirefarthest removed from P. This turn-buckle not only furnishes a means foradjusting the strain on the wire rope, Whichshould always be kept taut,but also offers a convenient irregularity in the Wire rope for grapplingby the locomotive. This spot corresponding to the end of the piston-rodis also the proper place for attaching the motive power.

E represents I the locomotive-tender, from which the wire rope R isgrappled or hooked on in any convenient way. I have shown a chain F,secured to the tender and securing with a slip-hook f to thechain-bridle G at H but this connection might be made in a number ofWays. The attachment at II should preferably be made self-detachin g ateach end of the stroke of the piston, so that the engine, having startedfrom the tank, need not stop.

The operation of my device is as follows: The locomotive having grappledR at H is moving in the direction shown by the arrow. The piston P ismoving inthe opposite direction, closing the valves in C and O3 andforcing the water before it up the pipes C2 and C*L into the tank T. Avacuum is created behind the piston, closing the valve in C3 and suckingwater up through O to fill the pumpbarrel behind the piston. It will beseen that as soon as the motion ot' P is stopped all the valves willclose and the piston will remain full of water. When P has reached oneend of its stroke, a car going in the opposite direc- IOO tion mayperform the reverse stroke; but the same result may be eected by runningthe car backward and forward a number of timesJ In Fig. l I have showntwo reservoirs, one at each end of the pump-barrel, which shortensconsiderably the length of the pipe connections; but one reservoir willanswer quite as Well. The sizeof the various pipes may be equal to orless than the pumpbarrel, as may be preferred.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent of the United States, is-

l. In a pump for raising Water near a railroad, the combination, with apump-barrel connected to a reservoir, of a piston fitting in saidbarrel, a Wire rope connected to both ends of said piston and forming aflexible pistonrod, and means for connecting said rope to a car on saidrailroad,substantiallyas described.

2. In apump for raising water near a railroad, the combination, with apump-barrel connected to a reservoir and discharging into a tank, of apiston tting in said barrel, a wire rope connected to both ends of saidpiston, running over sheaves or drums, and form.- ing an endlessilexible piston-rod, and means for connecting said rope to a car on saidrailroad, substantially as described.

3. In a pump for raising water near a railroad, the combination, with apump-barrel connected to a reservoir and discharging into a tank, of apist-on fitting in said barrel, two wire ropes under tension, eachsecured at one end to the said piston, passing through stuffing-boxesinthe opposite ends of said pumpbarrel, running over drums, and securedt0- ,piston P, Wire rope R, stufng-boxes S, turnbuckle H, drums D andD', and pipes C, C', G2, and C3, having Valves V opening upward,substantially asdescribed.

In testimony whereof I afix mysignature in presence of two witnesses.

CHARLES HODGSON.
